Locking engineered hardwood is a durable ﬂoor covering,

not intended as structural material. Locking engineered

hardwood requires a clean, dry, secure subﬂoor that meets

building codes. Locking engineered hardwood ﬂooring can

be installed above, on or below grade.

The following requirements are not intended to supersede

federal, state or local building codes, but as with many

other interior ﬁnish products, may require modifying

existing structural components for successful installation.

Owner assumes responsibility for compliance with all

building codes.

All work involving water or moisture (plumbing, masonry,

painting, plastering) must be completed prior to ﬂooring

installation. Building envelope must be complete and

exterior doors and windows installed. Exterior grading and

gutter downspouts should be completed and permanent

HVAC systems in operation.

Precautions should be taken to protect ﬂoors from other

trade work. Do not cover ﬂoors with plastic, red rosin, felt

or wax paper or previously used cardboard. Instead, use

a breathable material such as clean, dry, plain uncoated

cardboard or craft paper; inks from printed cardboard could

damage the hardwood ﬂoor. The ﬂoor should be thoroughly

cleaned before covering to remove grit and debris that

would damage the ﬁnish.

Locking Engineered Hardwood - Floor Installation Instructions

The ﬂoor must be completely covered to eliminate uneven ambering from exposure to UV light.

Locking engineered hardwood ﬂooring is suitable for use in climate controlled indoor installations only and should not be installed

over any ﬂoor with a sump pump or in a room with a ﬂoor drain. Room temperature should be 60-80°F, with relative humidity

between35-55%. These environmental conditions are speciﬁed as pre-installation requirements and must be maintained for the

life of the product. Additionally, any HVAC system must be in operation for a minimum of 14 days prior to performing moisture

tests or installation.

Building interiors are affected by two distinct humidity seasons–Heating and Non-Heating. Care should be taken to maintain

humidity levels between 35-55% year-round. As with all wood ﬂooring, expansion and contraction will be minimized if the interior

relative humidity is consistently maintained year-round. Humidiﬁcation and/or dehumidiﬁcation systems may be necessary to

maintain your home environment to prescribed relative humidity conditions.

All heating methods create dry, low humidity conditions. Humidiﬁers are recommended to prevent excessive shrinkage or

gapping in wood ﬂoors due to seasonal periods of low humidity.

During the non-heating season proper humidity levels should be maintained by using an air conditioner or dehumidiﬁer.

RADIANT FLOOR HEATING – This product can be used in combination with many types of in-ﬂoor heating. The heating system

can be cast in a concrete ﬂoor or in a thin layer of ﬁller on the surface of a concrete subﬂoor. It can also be installed under a

wood subﬂoor or installed on the surface of the subﬂoor as an electrical matting if it meets the ﬂoor ﬂatness requirements.

a. Follow the instructions from the supplier of the ﬂoor heating system.

b. Concrete subﬂoors must be installed and cured with no heat transfer for a minimum of 60 days.

c. The heating system must be in operation for at least two weeks before installation. The system may be turned off or

set to a suitable installation temperature (65 to 72°F).

d. The ﬂooring surface temperature, which is the surface of the subﬂoor or the heat radiating from electric heating mats,

should not exceed 84°F (29°C).

CAUTION – Excessive ﬂoor heating will damage ﬂooring planks. Radiant heating systems create dry heat that lowers interior

humidity levels. It may be necessary to add supplemental humidity in order to maintain recommended RH levels (35-55%) and

prevent damage to the wood ﬂoor.

A moisture test is strongly recommended to determine if high moisture exists in the subﬂoor. When using a calcium chloride

moisture test for concrete subﬂoors (ASTM F1869), values must be ≤ 5 lbs/1000ft

/24-hr or <80% RH with an in situ probe

(ASTM F2170). Moisture readings of wood subﬂoors must be ≤ 12%.

Acceptable job site conditions, including relative humidity and subﬂoor moisture conditions, must be maintained throughout the

lifetime of the ﬂooring.

This product is installed as a ﬂoating ﬂoor only and requires the use of T-moldings in doorways 4 ft (1.22m) or less and in rooms

40 feet (12.2 m) or larger in length or width. Floor movement must not be constrained by glue, nails, screws, hardware or other

ﬁxed obstructions.

This product must be installed in accordance with these installation instructions.

unevenness per 10-foot span.

d. Acclimate unopened product before installation for a minimum of 48 hours.

e. Clean debris from subﬂoor before installation.

f. For concrete subﬂoors, install vapor barrier with overlapped seams of 8" or more.

g. For planks without attached underlayment, install over single layer of underlayment appropriate for locking

engineered wood ﬂoors. For planks with attached underlayment, it is acceptable to install Pergo Gold

underlayment

(Lowes Part # 670312) prior to ﬂooring installation if desired.

h. Some cartons may include a starter/cut plank with a white label on the face. These planks are a conservation

measure to help reduce the waste of trees that contain natural imperfections. We recommend to cut the plank on

each side of the label to create two planks for starting and ﬁnishing a row during your installation. If the label is near

the end of the plank, you will only be able to cut on one side of the label. DO NOT install cut pieces less than 8” in

length. For more information call 1-800-33-PERGO or visit na.pergo.com/contact-us.

Locking Engineered Hardwood - Floor Installation Instructions

1. Inspect each plank. Floor should be installed blending planks from several cartons at the same time to ensure good color and

shade mixture throughout the installation.

2. For the ﬁrst row along straight walls, remove the tongue on all long side joints and on the short side of the 1st plank only.

3. For uneven walls, trace contour on tongue-side of plank and cut.

4. Assemble the ﬁrst row tongue side toward wall. Insert the end tongue into the end groove and rotate downward to assemble.

Keep the planks aligned and the joints closed.

5. Two spacers thick side to thick side = 3/8".

6. Provide a 3/8" space for expansion on all sides. First piece must be at least 8" long. Start new rows with pieces trimmed from

previous row or use a starter/cut plank from step H of site and material preparation. Ensure at least a 12" end joint offset.

7. At a slight angle, insert the tongue of plank 2 into the groove of plank 1 until the plank edges meet, and then rotate down until

the joints lock.

8. Join the short end of the plank ﬁrst. There will be a gap on the long side joints when the plank is rotated down.

9. Raise the outside edge of the plank upward approximately 1". Maintain this angle as you push the plank in until the plank

edges meet. Rotate the plank downward until the joint locks. Repeat these steps to complete the installation. Installation Tip:

Place a carton of planks across the end of the row being installed to keep installed planks in place during installation.

10. Alternate Tap Method: Align the tongues into the grooves of the long and short sides of the planks. Install the long side ﬁrst

by placing a tapping block no closer than 8" from either end and tap lightly along the long side until the joint is closed tightly.

Then tap the end using the tapping block into a locked position. Note: Uneven tapping or use of excessive force may damage

the joint.

11. Ensure there will be a 3/8" gap (after the joint is closed) to the wall for expansion.

12. For the last row, align the plank to be used on top of the 2nd to last row. Using a full width plank as a spacer, trace wall

contour and cut plank.

13. For the last row, install the long side tongue into the groove with the end joint aligned. Using a pull bar and hammer, work

evenly along the length of the plank and lightly tap the joint closed.

14. After tapping the long side joint closed, tap the short side closed, using a tapping block or a pull bar.

Installation Under Doorway Frames

15. Slide plank under pre-cut door frame.

16. Tap the long side joint closed ﬁrst. Then tap the end joint closed.

Installation Around Fixed Objects (such as Pipes)

17. Allow 3/8" expansion space around pipes or other ﬁxed objects.

18. Remove all spacers.

19. The entire perimeter of the installation must be sealed with Simple Solutions waterproof quarter round

(Lowe’s item # 3674489) or 100% silicone sealant in accordance with the installation instructions. For sections where

Simple Solutions waterproof quarter round cannot be used, seal the perimeter with 100% silicone sealant, as follows.

DO NOT use acrylic sealant.

• First ﬁll all expansion spaces with 3/8" compressible PE foam backer rod and cover with silicone sealant.

• Prior to installing the moldings, apply silicone sealant to the portion of the molding or transition that will contact directly

with ﬂooring surface.

• Install moldings and immediately wipe away any excess silicone sealant.

• Apply silicone at connections to doorframes or any other ﬁxed objects.

Place felt ﬂoor protectors under legs of moveable furniture. Chair casters should be rubber — not plastic or metal. Place walk-off

mats at entrances. Dust mop as primary cleaning method. Occasionally wet mop with water only, using a well wrung-out mop;

DO NOT pour liquid directly on ﬂoor or use an excessively wet mop that will puddle or leave moisture standing on the ﬂoor. If

needed, use a solution of 1 cup of vinegar per gallon of water OR 1/3 cup ammonia per gallon of water. DO NOT use detergents,

abrasive cleaners, soaps, waxes or polishes. A residential steam mop may be used provided the steam is applied to a microﬁber

pad and not applied directly to the ﬂoor. Make sure to set the temperature of the steam mop to the appropriate setting for

hardwood ﬂoors, or to the lowest setting. Steam mop in the length direction of the planks only. Use correct hard surface vacuum

tools. DO NOT use rotating beater bars, ﬂoor scrubbers, jet mops or similar products. Wipe up spills immediately. DO NOT allow

topical moisture to remain on the ﬂoor longer than the time speciﬁed in the product warranty.

Engineered hardwood reacts to sunlight. Hardwood contains certain types of acids in its cellular structure. With exposure to

sunlight these acids begin to amber. The color change is referred to as patina. The hardwood will reach its own natural warmth

and patina level and stop ambering. The amount of patina is directly related to the species, amount of acids and the level of

sunlight. The entire ﬂoor will reach the same patina level over time. This is often noticed after a rug is removed and the ﬂoor is

noticeably different in color underneath. If you remove the rug and expose the entire ﬂoor to the same amount of light, it will

even out over time and become uniform in color.

Care and Cleaning

• Cutting, sanding or machining wood products produces wood dust. While wood products are not hazardous under the OSHA

Hazard Communication Standard (29 CFR 1910.1200), the International Agency for Research on Cancer (IARC) and the state

of California have classiﬁed wood dust as a human carcinogen.

• Airborne wood dust can cause respiratory, skin and eye irritation. Power tools should be equipped with a dust collector. Use an

appropriate NIOSH-designated dust mask. Avoid dust contact with skin and eyes.

• In case of irritation ﬂush eyes with water. If needed seek medical attention. If dermatitis occurs, seek medical attention.

• PROPOSITION 65 WARNING: This product contains chemicals known to the state of California to cause cancer.

• The products in this carton DO NOT contain asbestos or crystalline silica.

• DO NOT MECHANICALLY CHIP OR PULVERIZE EXISTING RESILIENT FLOORING, BACKING, LINING FELT, ASPHALTIC

“CUTBACK” ADHESIVES OR OTHER ADHESIVES.

• DO NOT sand existing resilient tile, sheet ﬂooring, backing or felt linings. These products may contain asbestos ﬁbers that are

not readily identiﬁable. Inhalation of asbestos dust can cause asbestosis or other serious bodily harm. Check with local, state

and federal laws for handling hazardous material before attempting the removal of these ﬂoors.

Locking Engineered Hardwood - Floor Installation Instructions

The owner/installer assumes all responsibility for ﬁnal inspection of product quality. Examine ﬂooring for color, ﬁnish and

style prior to installation. If material is unacceptable, contact the seller immediately. Wood is a natural product and contains

characteristics such as variations in color, tone and graining. Flooring is manufactured in accordance with industry standards,

which allows manufacturing and natural deﬁciency tolerances up to 5% of the total installation. Installer should work from

minimum of 3 cartons at the same time to ensure good color and shade blend. The installer must use reasonable selectivity and

hold out or cut off piece with deﬁciencies. DO NOT install undesirable pieces. Flooring warranties DO NOT cover materials with

visible defects once they are installed. Installation is acceptance of product quality.

It is the responsibility of the installer and owner to ensure that jobsite, environmental, subﬂoor and subsurface conditions

involved meet or exceed all requirements as outlined in installation instructions prior to installation. Manufacturer declines

all responsibility for product performance or installation failure due to subﬂoor, substrate or environmental deﬁciencies or

jobsite conditions.

For service under the warranty please contact your local Lowe’s store. Describe the problem and in many cases, they can

provide you with a solution.

For installation, maintenance and technical questions please call 1-800-33-PERGO.
